    I thought I'd mention that I got the latest OS X installed on my old 2006 Mac Pro 1,1. It's not supported by default because of its original video card (mine's been upgraded) and its 32-bit EFI. Well, smart hackers out there have written a bit of software to trick the new system into communicating with that 32-bit EFI as if it were 64-bit, and all is well!

    It's not for someone with no tech savvy, unfortunately, as it means doing some 'hacking' of the installation files after "restoring" the installer disk image to a physical volume (USB drive or hard drive). Here is a link with instructions about it, though:

    It's good for a number of systems that are not officially supported. The list at the link is:

    -MacBook2,x
    -MacBook3,x
    -MacBook4,x
    -MacBookPro2,x
    -MacBookAir1,1
    -MacMini1,x (C2D upgraded)
    -MacMini2,x
    -iMac4,x (C2D can be upgraded)
    -iMac5,x

    But that should also include Mac Pro 1,1 and 2,1. Not sure why they didn't list those there.

    But anyway, it's working very well for me. They even have a little script available to make sure that system updates won't permanently replace the modified boot file, which would otherwise cause the installed system to cease booting up! I recommend anyone wanting to keep an older machine going consider doing this. If I hadn't done this, the latest version I'd be able to run on there would be 10.7 Lion, and that version was kind of yucky. I ran Mavericks for a while through basically the same trick, and that likewise worked great. I never bothered trying it with 10.8 Mountain Lion, though.
